Re-installing my single coil bass pickup

I recently got a used custom bass from a friend. It is very similar to the Fender Sting signature bass. It has one single coil pickup and 2 nobs (one for volume, one for tone) Sadly, none of it was wired and I need some help figuring out how to do it.

Attached is a picture of the pickup. As you can see, there is a red wire, a white wire, and a blue wire. How should these be wired through the controls to the cord input jack? (diagram(s)/schematics preferred)

Also, I plan to replace the two potentiometers for vol. & tone. What levels should the pots that I replace them with run at?

i'm not sure why your pickup has 3 wires coming from it...maybe one is a goofy ground wire....
perhaps upgrade and get a more standard Seymour Duncan single coil pickup... i think they have 3 models.
